TodZ'Z whom it maycomm" 'Blit'known" thatLJOHN BRIG/HARD, a citiienofthe United States, residing at New Holstein, in the county of Calumet,State of Wisconsin, have 'inventedbertain new and useful Improvements inMilk- Strainers and I do, hereby declare" the "following to be a full,clear, and exactdescription of the invention, such as will enableothers'skilled in the art to whichit appertainsto make and use the same.

,This invention relatesto milk strainers for dairy use.

The object of the an improved form of milk strainer which is adaptableto milk cans of various types. Milk can constructions have recentlyundergone certain modifications from the old standards, so that the topsof the cans in the newer form are provided with a larger opening thanthe older form. My invention provides a strainer which is adaptable toboth forms of milk cans so that it may completely cover the mouth ofeither style .Of can with such a fit as to exclude dirt, bugs and strawfrom the cans. Also, the invention contemplates a strainer from which asection may be removed for use in straining milk into small cream cans.

WVith the above objects in view, and such others relating to the detailsof construction, as may hereinafter appear, my invention will now befully set forth and described, reference being had to the accompanyingdrawings.

Inthe drawings Figure 1 is a vertical section through a milk can of thenewer type showing my invention applied thereto,

Fig. 2 is a similar section of a portion of a milk can of the oldertype, showing my invention in use thereon,

Fig.3 is a vertical section through the assembled strainer,

Fig. 4 is a plan view of the cover section of the strainer, and

Fig. 5 is an elevation of the strainer section alone.

Referring more particularly to the drawings, 1 represents the top of amilk can.

of the new type upon whose rim the cover section 2 is seated. The coversection 2 is formed from a disk which is slightly dished with a gradualincline toward a central opening 3. Around the margin of the coversection 2 there is formed a rim or flange 4:

invention is to provide" which is soshaped' as to'provide a shoulder orseat 5 along the margin of the cover sectionw'hich the base of theflange l over.- hangs, the seat 5 being adapted to'be en gaged'withjthe' 'margin 'fofthe milk can openinginfittedrelation, The flangehis furthermore upwardly directed away" from thes'eat' 5 so'th'atit'rises'above the outer or convex surface of the disk? Fitted throughthe, opening 3 in the centerofithe disk is a sleeve 'or' "collar '6,"said sleeve "0 1- collar .6 extending in both directions away from theopening '3 in flange-likerelation 'to provide a seat or socket withinwhich the spout 7 of the strainer 8 is removably fitted.

The strainer 8 is formed of a bowl 9 which rises from the spout 7, thebottom of the bowl having a central opening 10 which is smaller than thecross sectional area of the spout 7, so that the milk is de-; liveredfrom the bowl into the center of the spout without first coming intocontact with the inner wall of the latter. A strainer fabric '11 of anysuit-able material is exlspecification of tt r iie er t- PatentedDecflO,

tended across the opening 10, and may, if-

desired, be held in position by means of a removable clamping ring 12.

The spout 7 is of practically the same length as the sleeve 6, and maybe inserted therein from either end, the sleeve providing a solid seatfor the strainer section, and

milk will flow freely into the cans from the strainer. y

In the positions shown in Fig. 1, "the seat 5 fits into the margin ofthe can top, the disk thenrlsing above the can top by reason of itsdished or concavitalconstruction. The strainer spout when inserted intothe sleeve 6 has its lower end coincided with the lower end of thesleeve, so that the milk flows directly off of the end of said sleeveinto the can without coming into contact with the inner surface of thecover section so as to flow toward the edge thereof;

When used with a can of the older type,

as indicated in Fig. 2, the convexed side of the disk is seated uponthe-top or rim of the can, with the projecting portion of the' flange 4brought into such contact with-the rim as to exclude the dirt and strawfrom the can. Obviously, in this case, the'strainer 8 is inserted intothe reverse end of the sleeve 6 and hereto the milk is prevented fromcoming into contact With the jaw "of' lVhen it is desired to fill tincans the disk. by the use of the strainer,. the strainer section aloneis used, the spout 7 being of such dimension. that it .Will fit Withinthe standard, cream can top.

, It will be apparent from the foregoing description that I haveprovided a Very practical and efficient strainer which may be usedwithequal facility upon 01d and new type cans, not only to eflicientlystrain the milk, but to exclude dirt, straw andinsects from cans ofequal. type; a,

spout of less diameter then the element and depending therefromconcentrically of the bottom opening to removably telescope avithin theflanged opening of said cover section, and a strainer fabric coveringthe bottom opening in said element, the spout Copies of this patent maybe obtaineddor five cents each; by addressing the Commissioner ofPatents,
